Hi All,
we are actually troubleshooting an perforamnce problem.
There is an Sync Copy top Tape ( LTO 8 )
2 Mediaagents in a ms csv cluster.
When we use combinded streams 1 and multiplexing 1 we only get max 400GB/H troughput the normal jobs have 100GB/h mixed data.
If we increase the multiplexing to 8 and combided to streams 1 the performence grows up over 1500GB/h .
so i have 2 Questions:
- Is there an limitaion in the stream troughput ? So can 1 Stream only use x GB/h
- Wich impact has the multiplexing on tape for the DR Restore process, Does it realy impact the performance so the tape getting in wind/rewind process ?
